This command deletes the	delete public-key username [dsa rsa]

key.	Range: 1-8 characters
	• dsa – DSA public key type.
	• rsa – RSA public key type.
	Default Setting: Deletes both the DSA and RSA key.
	Command Mode: Privileged Exec
	Example:
	Console#delete public-key admin dsa
	Console#
ip ssh crypto host-key	Syntax:

This command generates	• dsa – DSA (Version 2) key type.

lic and private).	Default Setting: Generates both the DSA and RSA key pairs.
	Command Mode: Privileged Exec
	Command Usage:
	• This command stores the host key pair in memory (i.e., RAM). Use the ip ssh
	save host-key command to save the host key pair to flash memory.
	• Some SSH client programs automatically add the public key to the known hosts
	file as part of the configuration process. Otherwise, you must manually create a
	known hosts file and place the host public key in it.
	• The SSH server uses this host key to negotiate a session key and encryption
	method with the client trying to connect to it.
	Example:
	Console#ip ssh crypto host-key generate dsa
	Console#
ip ssh crypto zeroize	Syntax:
This command clears the	ip ssh crypto zeroize [dsa rsa]
host key from memory (i.e.	• dsa – DSA key type.
RAM).	• rsa – RSA key type.
	Default Setting: Clears both the DSA and RSA key.
	Command Mode: Privileged Exec
	Command Usage:
	• This command clears the host key from volatile memory (RAM). Use the no ip
	ssh save host-key command to clear the host key from flash memory.
	• The SSH server must be disabled before you can execute this command.
	Example:
	Console#ip ssh crypto zeroize dsa
	Console#
ip ssh save host-key	Syntax:
This command saves host	ip ssh save host-key [dsa rsa]

memory.	• rsa – RSA key type.
	Default Setting: Saves both the DSA and RSA key.
	Command Mode: Privileged Exec
	Example:
